13. Magia e ecologia : a procura da regularidade na natureza
The way of which occurs the relation to Nature presents distinct aspects to different societies. However, a common mark can be signaled among them: the search of regularity in the phenomena of natural world, as a way of assuring the continuit of their existence. Nature s controI constitutes itself as the route fiom which people expect to obtain this regulari

14. Preparação, caracterização, reações de intercalação e decomposição termica de hidroxidos duplos e amelares contendo Cd, Mg e Zn
In this work we have prepared Layered Double Hydroxides (LDH) using different divalent metals, aluminium as the trivalent metal, and nitrate and carbonate as the counter anions. These LDHs are bidimensional compounds which alternate positively charged layers formed by the metal atoms and hydroxyl groups and negatively charged layers formed by the counter ani

15. A Bayesian framework for combining heterogeneous data sources for gene function prediction (in Saccharomyces cerevisiae)
Genomic sequencing is no longer a novelty, but gene function annotation remains a key challenge in modern biology. A variety of functional genomics experimental techniques are available, from classic methods such as affinity precipitation to advanced high-throughput techniques such as gene expression microarrays. In the future, more disparate methods wil

16. Quantitative neuropathology by high resolution magic angle spinning proton magnetic resonance spectroscopy
We describe a method that directly relates tissue neuropathological analysis to medical imaging. Presently, only indirect and often tenuous relationships are made between imaging (such as MRI or x-ray computed tomography) and neuropathology. We present a biochemistry-based, quantitative neuropathological method that can help to precisely quantify information

17. Study of lignification by noninvasive techniques in growing maize internodes. An investigation by Fourier transform infrared cross-polarization-magic angle spinning 13C-nuclear magnetic resonance spectroscopy and immunocytochemical transmission electron microscopy.
Noninvasive techniques were used for the study in situ of lignification in the maturing cell walls of the maize (Zea mays L.) stem. Within the longitudinal axis of a developing internode all of the stages of lignification can be found. The synthesis of the three types of lignins, p-hydroxyphenylpropane (H), guaiacyl (G), and syringyl (S), was investigated in
